This series adds multicast and broadcast packet transmission support to
the ovpn DCO driver. It is a v5 of the broadcast feature patch, now
accompanied by selftests.

This series is based on top of:

  ovpn: disable BHs when updating device stats
  https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=0c0dddc07d27

which introduces ovpn_dev_dstats_tx_dropped() / ovpn_dev_dstats_rx_dropped()
helpers.  The broadcast worker uses these helpers instead of open-coding
local_bh_disable()/local_bh_enable().
